Read online book Urban DC Microgrid : Intelligent Control and Power Flow Optimization by Manuela Sechilariu MOBI
9780128037874 English 0128037873 Urban DC Microgrid, Urban DC Microgrid: Intelligent Control and Power Flow Optimization focuses on microgrids for urban areas, particularly associated with building-integrated photovoltaic and renewable sources. This book describes the most important problems of DC microgrid application, with grid-connected and off-grid operating modes, aiming to supply DC building distribution networks. The book considers direct current (DC) microgrid to supply DC building distribution networks for positive energy buildings; dynamic interactions with the utility grid based on communication with the smart grid; supervisory control systems; and energy management. The global power system is exposed and the DC microgrid system is presented and analysed with results and discussion, highlighting both the advantages and limitations of the concept. Coverage at the system level of microgrid control as well as the various technical aspects of the power system components make this a book interesting to academic researchers, industrial energy researchers, electrical power and power system professionals. Provides a strong overview of microgrid modelling Describes the most important problems of DC microgrid application, with grid-connected and off-grid operating modes, aiming to supply DC building distribution networks Offers experimental problem examples and results Includes supervisory control and energy management, Urban DC Microgrids focuses on microgrids for urban areas, particularly associated with building-integrated photovoltaic and renewable sources.

Strong overview of microgrid modelling Offers experimental problem examples and results Includes supervisory control and energy management, Urban areas have great potential for photovoltaic (PV) generation; however, direct PV power injection has limitations for high level PV penetration. It induces additional regulations in grid power balancing because of lacking abilities of responding to grid issues such as reducing grid peak consumption or avoiding undesired injections. The smart grid implementation, which is designed to meet these requirements, is facilitated by microgrids development. The book explores most of the widely-used sources for DC microgrid, including photovoltaic sources, electrochemical storage, utility grid connection, diesel-generator, and gives the supervisory control design for both operating modes on-grid and off-grid. The multilayer supervisory system handles instantaneous power balancing following the power flow cost optimization while providing interface for smart grid communication. The optimization takes into account forecast of power production and load power demand, and handles constraints such as storage capability, grid power limitations, grid time-of-use pricing, grid peak hour, and diesel generator fuel consumption. Simulation (MATLAB/ Simulink) and experimental test results are presented to demonstrate the effectiveness and the relevance of the proposed DC microgrid designed for urban area. Valuable experimental results allow discussions, analysis and define perspectives. Facing to other books mostly seen as several scientific and technical works compiled by editor(s), this book was written by two authors in a uniform writing style either for the theme homogeneity or phenomena explications. Wishing to publish a relatively comprehensive DC microgrid study dedicated to urban areas with a clear and rigorous exposition of building-integrated microgrid, this book fills the gap between microgrids architectures and power management general textbooks and the large scale microgrids and hierarchical control specialist textbooks which are written with useful detail for power converters' application. It is a useful reference for graduate students and young scientists in universities as well as all professionals and electrical engineers engaged in electrical power equipment/systems design, integration, and management. Contains step-by-step research work on modeling, simulation, and implementation of DC building-integrated microgrid Addresses a systemic approach to design a DC microgrid and covers topics such as photovoltaic, back-up sources, utility grid, power management and control Introduces an intelligent control which handles instantaneous power balancing following the power flow cost optimization while providing interface for smart grid communication Formulates optimization considering forecast of power production and load power demand, and constraints such as storage capability, grid power limitations, grid time-of-use pricing, and energy costs Provides many experimental results to demonstrate the effectiveness and the relevance of the proposed system Presents research work on urban DC microgrid written in a uniform writing style, either for the subject homogeneity or phenomena explications, in contrast of works compiled by editor(s)
